Multifunctional Roles and Ecological Implications of Nano-Enabled Technologies in Oryza sativa Production Systems: A Comprehensive Review
Summary
This review examined the use of nano-enabled technologies in rice farming, covering their roles in boosting plant resilience, nutrient uptake, and the efficiency of fertilizers and pesticides. Researchers identified nanoplastic pollution as an emerging concern within agricultural systems alongside more established issues like heavy metal stress. The study calls for standardized environmental risk assessments before these technologies can be widely adopted in food production.
Micro-nanomaterials have garnered significant attention in rice (Oryza sativa L.) cultivation due to their unique physicochemical properties. This study reviews the multifunctional applications of micro-nanomaterials in enhancing rice resilience, promoting nutrient uptake, improving photosynthetic efficiency, and increasing the utilization rates of fertilizers and pesticides. Using keyword and clustering analyses, this review identifies key research hotspots and emerging trends in the field, including heavy metal stress, nanoplastic pollution, and biochar applications. While early studies predominantly focused on the synthesis and characterization of these materials, recent research has shifted towards evaluating their comprehensive ecological impacts on rice production systems. Despite the promising potential of micro-nanomaterials in improving rice yield and quality while supporting sustainable agriculture, concerns about their long-term accumulation in ecosystems and potential toxicity remain unresolved. Future research should prioritize the development of cost-effective, efficient, and environmentally friendly micro-nanomaterials and establish standardized frameworks for ecological risk assessments to facilitate their large-scale agricultural application. This study provides theoretical insights and practical references for advancing micro-nanotechnology in global food security and sustainable agriculture.
